CALEB S. GURNEY, OF PORTSMOUTH, NEW HAMPSHIRE.

UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 722,229, dated March 10, 1903.

Application filed June 20, 1902. Serial No. 112,619. (No model.)

T (0 whom it may concern.-

Beit known that I, CALEB S. GURNEY, acitizen of the United States, residing at Portsmouth,in the county of Rockingham and State of New Hampshire, have invented a new and useful Umbrella, of which the following is a specification.

This invention relates to umbrellas, and has for its object the construction of a means whereby the ribs and braces are coupled to the standard and the braces coupled to the ribs in a simple, inexpensive, and durable manner, and that will not be liable to become broken or disarranged.

The invention consists in certain novel features of the construction,as hereinafter shown and described, and specified in the claim.

In the drawings, illustrative of the invention, Figure 1 is a side view of a portion of an umbrella frame embodying the improvements. Fig. 2 is an enlarged detail view of the lower member of the notch-piece. Fig. 3 is an enlarged perspective view of the upper Fig. 4 is an enlarged sectional detail of the notch-piece and the runner. Fig. 5 is a plan view of the lower member of the brace-coupling. Fig. 6 is an enlarged transverse section on the line VI VI of Fig. 1. Fig. '7 is a perspective View, enlarged, of the coupling between the rib and the brace. Fig. 8 is a perspective View of a portion of one of the braces.

The device may be attached to any form of umbrella or parasol standard and will employ the ordinary ribs and braces. The standard is represented at 10, and embracing this standard at the point where the upper ends of the ribs are usually united is a notch member 11, with its lower end turned outward and formed with a series of spaced semisookets 11 the sockets each being in the form of one-half of an elliptical cavity with a contracted aperture 11, as shown.

Surrounding the standard 10 above the notch member 11 is another notch member in the form of a sleeve 11', also provided with semi-elliptical half-sockets 11 corresponding to and registering with the sockets 11, so that when the two notch members are united upon the standard, as in Figs. 1 and 4, a series of elliptical sockets will be formed encircling the standard, as indicated in Fig. 2.

The ribs are indicated at 12, and each rib will be provided with an elliptical or oval head 12, adapted to engage the sockets 11 11, with the portion of the rib next the head 12 preferably flattened and widened, as at 12, and adapted to engage the contracted apertures 11, as shown in Figs. 4 and 5. By this means the ribs are supported movably between the notch members and are free to move vertically, but will be prevented from rotary movement by the elliptical heads 12, engaging the corresponding elliptical sockets, together with the flattened portions, which coact with the elliptical heads to assist in holding the parts in vertically-movable engagement. The notch members 11 11 will be firmly attached to the standard 10 by any suitable meanssuch as pins 13 13. The ferrule 11, with its extended socket member 11, will be stamped or otherwise formed of a single piece, preferably of sheet metal, of uniform thickness throughout, while the ferrule member ll will be similarly formed, so that these parts of the structure will combine strength and lightness, and consequent cheapness and durability. The ribs are thus supported in place independently and Without the use of the rivets, binding-wires, or other means usually employed for securing the ribs in umbrellas.

Slidably disposed upon the standard 10 below the notch member 11 are two other similar notch members 14 14, forming the runner, the member 14 having laterally-extended semispherical sockets 14', similar to the sockets 11 on the notch member 11, except that the cavities therein are semispherical instead of being semi-elliptical,and the runner member 14 having the semispherical socket 14 and contracted aperture 14, similar to the notch member 11 and the aperture 11 as shown, except that the aperture is in the upper runner member instead of in the lower runner member.

The braces are represented at 15 and each provided with a spherical head 15, adapted to engage the spherical sockets between the two runner members 14 14, as shown, the shanks of the braces next the heads 15' engaging the apertures 14. By this means the braces are movably connected to the slidable runner and free to move vertically and also free to rotate in the sockets, but will be retained therein against end movement.

The two parts of the runner 14 14. will be connected together, as by rivets 14:, but will be slidable upon the standard in the same manner and for the same purpose as the ordinary slidable runner of the ordinary umbrella.

The standard will be provided with the usual spring-supported clip 16, by which the runner 14 14 will be supported in its elevated position, as indicated in 1 and 4.

The outerends of the braces will be formed with T-heads 17, adapted to engage couplingplates 18, embracingthe ribs 12 intermediate of their lengths at the usual points where the braces are connected to the ribs of umbrellas. Between the T-heads 1'7 and the ribs 12 the two parts of the couplings 18 are united by rivets 19, whereby the couplings are firmly clamped to the ribs and at the same time prevented from spreading and disengaging the T-heads. The braces 15 are thus supported vertically movable around the T heads as centers, but will be prevented from turning in or becoming detached from the couplings. This makes a very complete, simple, and durable coupling, readily applied and requiring no extra pins or rivets in the movable parts to become worn by friction or broken by the strains to which they will be subjected.

The heads 17 will preferably be formed integral with the braces 15 and will therefore not be weakened by any wear to which they will be subjected or weaken the ribs by the fact of their being attached thereto. The

whole device is therefore a very complete, cheap, and durable structure, formed in few parts, easily repaired, and any part easily renewable.

' The invention can be applied to any umbrella, parasol, or sunshade and may be modified as to sizes and dimensions without departing from the spirit of the invention or sacrificing any of its advantages.

It will be noted that the contracted portion 12 of the ribs 12 is widened, as well as fiattened, to retain the area of the rib, so that the rib is not weakened at this point by the change of form. By this means also the contracted portions 11 may be reduced in width, and thereby correspondingly increase the gripping lengths of the elliptical heads 12, and not only increase the strength of the notch, but also increase the size of the elliptical head, and consequently the strength of the joint.

Having thus described my invention, what I claim is In an umbrella, the combination with a rib pivotally connected to a centrally-disposed standard,of a clamp comprising a metal plate bent around the rib to enclasp the same and form a pair of arms spaced apart, said arms provided with juxtaposed transverse perforations near their outer ends, a brace pivotally connected to said standard and having formed on its outer end an integral T-head adapted to engage the perforations in the clamp, and a transverse rivet connecting the spaced arms of the clamp; whereby said arms will tightly engage the T-head to prevent its accidental escape but may be sprung apart to release the same when desired.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CALEB S. GURNEY.
